Domestic Hot Water Heaters and Boilers

FTIIC-12R

Features and Benefits

Low NOx, High Efficiency, Hot Water Supply and Hydronic Heating Boilers

Futera II Series hot water supply boilers provide dependable

performance with 85% near condensing efficiency, with industry-

leading NOx levels of less than 10 ppm.

Quality components include a rugged heat exchanger that prevents

rust and corrosion for the life of the heater. Finned tubes are industrial

grade copper with fins and tubewalls formed as one, providing

optimum heat transfer. Each tube is rolled into either all-bronze

headers – standard on all Futera II water heaters

or cast iron headers – standard on all Futera II

boilers. The tubes are individually field replaceable.

The heat exchanger is superior in design, durability and

serviceability – each is hydrostatically tested, approved

and stamped for 160 psi ASME operation.

Futera II Series boilers and water heaters are also available with corrosion-resistant, brushed stainless steel jacket. Ideal for outdoor or indoor installation in harsh environments such as coastal areas and processing applications requiring wash down.

Advanced Diagnostic SystemThe Futera II features an easy-to-read LCD display that provides

clear indication of inlet water temperature or setpoint in Fahrenheit

or Celsius. The display also provides information for setting

temperature control parameters. Advanced troubleshooting and

self-diagnostic control provides a step-by-step cycle of operation.

Each step is automatically tested and indicated, allowing for

simplified and less costly troubleshooting.

Proven Pilot Ignition SystemThe Futera II Series uses a proven pilot with interrupted spark

ignition and UV flame detection. The UV detector and igniter

assembly provide highly reliable ignition and easy service.

This important design feature provides long-life reliability. An

observation port allows easy inspection of the flame at the top of

the boiler.

The Turbo Pilot®: Reliability At Its BestFutera’s independent “Turbo-Pilot” system with UV detection is

far more durable and reliable than any competitive ignition system

available today.

At 8,000 btu’s the “Turbo-Pilot” provides

a sure-fire source for burner ignition.

Smart Service DesignA Honeywell RM Series Flame Safeguard, limit controls and terminal

strips are neatly arranged and easily accessible in the front-facing panel.

RBI Temperature ControllerSP Setpoint or Target

Temperature:

The Setpoint is the inlet water

temperature that the operating

control will try to match by staging

the boiler between ‘Off’, ‘Stage 1’ and ‘Stage 2.’

D1 Boiler Differential:The boiler differential is centered around the setpoint so that when the sensor reads 1/2 of D1 below the setpoint, Stage 1 will be energized. When the sensor reads a temperature 1/2 of D1 above the setpoint, stage will turn off.

D2 Interstage Differential:The Interstage Differential is the difference in temperature between Stage 1 being called on, and Stage 2 being called on.
